4

the procurement of repairs, transportation or insurance); and, except to the extent that the effect of such payment would be to render any loan or forbearance of money usurious or otherwise illegal under any applicable law, Debtor shall thereupon pay Secured Party on demand the amount of all moneys expended and all costs and expenses (including reasonable attorneys’ fees) incurred by Secured Party in connection with or as a result of Secured Party’s performing or observing such agreements or taking such actions, together with interest thereon from the date expended or incurred by Secured Party at the highest rate then applicable to any of the Obligations. To facilitate the performance or observance by Secured Party of such agreements of Debtor, Debtor hereby irrevocably appoints (which appointment is coupled with an interest) Secured Party, or its delegate, as the attorney-in-fact of Debtor with the right (but not the duty) from time to time to create, prepare, complete, execute, deliver, endorse or file, in the name and on behalf of Debtor, any and all instruments, documents, financing statements, termination statements for filings not permitted under this Agreement held by other secured parties, applications for insurance and other agreements and writings required to be obtained, executed, delivered or endorsed by Debtor under this Section 3.

4.                                      Account Verification and Collection Rights of Secured Party. Secured Party shall have the right to verify any accounts in the name of Debtor or in its own name; and Debtor, whenever requested, shall furnish Secured Party with duplicate statements of the accounts, which statements may be mailed or delivered by Secured Party for that purpose.  Secured Party may at any time (both before and after the occurrence of an Event of Default) notify any account debtor, or any other person obligated to pay any amount due, that such chattel paper, account, or other right to payment has been assigned or transferred to Secured Party for security and shall be paid directly to Secured Party. If Secured Party so requests at any time, Debtor will so notify such account debtors and other obligors in writing and will indicate on all invoices to such account debtors or other obligors that the amount due is payable directly to Secured Party. At any time after Secured Party or Debtor gives such notice to an account debtor or other obligor, Secured Party may (but need not), in its own name or in Debtor’s name, demand, sue for, collect or receive any money or property at any time payable or receivable on account of, or securing, any such chattel paper, account, or other right to payment, or grant any extension to, make any compromise or settlement with or otherwise agree to waive, modify, amend or change the obligations (including collateral obligations) of any such account debtor or other obligor.

5.                                      Assignment of Insurance. Debtor hereby assigns to Secured Party, as additional security for the payment of the Obligations, any and all moneys (including but not limited to proceeds of insurance and refunds of unearned premiums) due or to become due under and all other rights of Debtor under or with respect to, any and all policies of insurance covering the Collateral, and Debtor hereby directs the issuer of any such policy to pay any such moneys directly to Secured Party. Both before and after the occurrence of an Event of Default, Secured Party may (but need not), in its own name or in Debtor’s name, execute and deliver proofs of claim, receive all such moneys, endorse checks and other instruments representing payment of such moneys, and adjust, litigate, compromise or release any claim against the issuer of such policy.

6.                                      Events of Default.  “Events of Default” in this Agreement means any of the following events:

5

(a)                                 Debtor fails to pay when due any principal, interest, fees or other payments due under the Secured Note or any other indebtedness of Debtor to Secured Party, whether any such indebtedness is now existing or hereafter arises and whether direct or indirect, due or to become due, absolute or contingent, primary or secondary or joint or joint and several;

(b)                                 Debtor and/or Guarantor (as defined in the Loan Agreement) shall fail to perform or comply with any of the covenants, conditions or agreements to be observed or performed by it under this Security Agreement, and/or the Secured Note, and/or the Loan Agreement as described in the Secured Note, or any credit or similar agreement between Debtor and/or Guarantor and Secured Party for a period of twenty (20) days after written notice of such default given by Secured Party and/or Guarantor;

(c)                                  This Security Agreement and/or the Secured Note, and/or the Loan Agreement as described in the Secured Note, cease(s) to be in full force and effect or is declared null and void or the validity or enforceability hereof and/or thereof is contested or challenged by Debtor or any of its members;

(d)                                 If a garnishment summons or a writ of attachment is issued against or served upon Secured Party for the attachment of any property of Debtor in Secured Party’s possession or any indebtedness owing to Debtor;

(e)                                  If a petition is filed by or against Debtor and/or Guarantor under the United States Bankruptcy Code, or if a trustee, receiver or similar officer is appointed for Debtor and/or Guarantor or for the property of Debtor and/or Guarantor, and in the case of any such action or proceeding commenced against any such party, such action or proceeding is not dismissed within 60 days; or

(f)                                   If the Secured Party shall at any time have reasonable grounds to believe that the prospect of due and punctual payment of any of the obligations of the Debtor now or hereafter existing under, or pursuant to, this Security Agreement, and/or the Secured Note is impaired.

7.                                      Remedies upon Event of Default. Upon the occurrence of an Event of Default under Section 6 and at any time thereafter, Secured Party may exercise any one or more of the following rights and remedies: (i) declare all unmatured obligations pursuant to the Note and/or this Agreement to be immediately due and payable, and the same shall thereupon be immediately due and payable, without presentment of other notice or demand; (ii) exercise and enforce any or all rights and remedies available upon default to a secured party under the Uniform Commercial Code, including but not limited to the right to take possession of any Collateral, proceeding without judicial process or by judicial process (without a prior hearing or notice thereof, which Debtor hereby expressly waives), and the right to sell, lease or otherwise dispose of any or all of the Collateral, and in connection therewith, Secured Party may require Debtor to make the Collateral available to Secured Party at a place to be designated by Secured Party that is reasonably convenient to both parties, and if notice to Debtor of any intended disposition of Collateral or any other intended action is required by law in a particular instance, such notice shall be deemed commercially reasonable if given (in the manner specified in Section 10) at least 10 calendar days prior to the date of intended disposition or other action; (iii) exercise or enforce

6

any or all other rights or remedies available to Secured Party at law, equity, or agreement against the Collateral, against Debtor or against any other person or property.

8.                                      Other Personal Property. Unless at the time Secured Party takes possession of any tangible Collateral, or within seven days thereafter, Debtor gives written notice to Secured Party of the existence of any goods, papers or other property of Debtor, not affixed to or constituting a part of such Collateral, but that are located or found upon or within such Collateral, describing such property, Secured Party shall not be responsible or liable to Debtor for any action taken or omitted by or on behalf of Secured Party with respect to such property without actual knowledge of the existence of any such property or without actual knowledge that it was located or to be found upon or within such Collateral.

9.                                      Miscellaneous. This Agreement does not contemplate a sale of accounts, payment intangibles or chattel paper. This Agreement can be waived, modified, amended, terminated or discharged and the Security Interest can be released, only explicitly in a writing signed by Secured Party. A waiver signed by Secured Party shall be effective only in a specific instance and for the specific purpose given. Mere delay or failure to act shall not preclude the exercise or enforcement of any of Secured Party’s rights or remedies. All rights and remedies of Secured Party shall be cumulative and may be exercised singularly or concurrently, at Secured Party’s option, and the exercise or enforcement of any one such right or remedy shall neither be a condition to not bar the exercise or enforcement of any other. All notices to be given to Debtor shall be deemed sufficiently given if delivered or mailed by registered or certified mail, postage prepaid, to Debtor at its address set forth above or at the most recent address shown on Secured Party’s records. Secured Party’s duty of care with respect to Collateral in its possession (as imposed by law) shall be deemed fulfilled if Secured Party exercises reasonable care in physically safekeeping such Collateral or, in the case of Collateral in the custody or possession of a bailee or other third person, exercises reasonable care in the selection of the bailee or other third person, and Secured Party need not otherwise preserve, protect, insure or care for any Collateral. Secured Party shall not be obligated to preserve any rights Debtor may have against prior parties, to realize on the Collateral at all or in any particular manner or order, or to apply any cash proceeds of Collateral in any particular order of application and Secured Parry may disclaim any and all implied warranties (as imposed by law) in connection with the disposition of Collateral. This Agreement shall be binding upon and inure to the benefit of Debtor and Secured Party and their respective heirs, representatives, successors and assigns and shall take effect when signed by Debtor and delivered to Secured Party, and Debtor waives notice of Secured Party’s acceptance hereof. Secured Party may execute this Agreement if appropriate for the purpose of filing, but the failure of Secured Party to execute this Agreement shall not affect or impair the validity or effectiveness of this Agreement. This Agreement shall be governed by the internal laws of the State of Minnesota.  If any provision or application of this Agreement is held unlawful or unenforceable in any respect, such illegality or unenforceability shall not affect other provisions or applications that can be given effect and this Agreement shall be construed as if the unlawful or unenforceable provision or application had never been contained herein or prescribed hereby. All representations and warranties contained in this Agreement shall survive the execution, delivery and performance of this Agreement and the creation and payment of the Obligations. Debtor hereby irrevocably submits to the jurisdiction of any Hennepin County,

7

Minnesota District Court, any Federal District Court in the District of Minnesota, over any action or proceeding arising out of or relating to this Agreement and agrees that all claims in respect of such action or proceeding may be heard and determined in any such court.
